Wheat and oilseed flax straws were studied as raw material for papermaking. Two different aspectswere investigated to valorize these agricultural byproducts: the capacity to recover some phenoliccompounds and the use of the resulting cellulose fibers in papermaking. Straw phenolic compoundcomposition was analyzed to determine the different accessible molecules and their available quantity.Ferulic acid, coumaric acid, vanillic acid, and vanillin were found in both wheat and oilseed flax straws.To enhance the release of these phenolic compounds, enzymatic treatments with feruloyl esteraseand xylanase, two enzymes known for their role in lignin destructuration, were tested. These treatmentsincreased the amount of phenolic compounds released, destructured hemicellulose and lignin, andimproved the soda cooking conditions of pulps with the reduction of chemical charge need in thepapermaking process. Phenolic compound production from this process could enhance the cost-effectiveness of papermaking from annual plants.Keywords: Wheat straw; oilseed flax straw; lignin; pulp and paper; phenolic compounds
